Abstract
In order to increase the heat exchange capacity and efficiency of a cooling fin for an automotive radiator, air conditioner heat exchanger, or the like, a plurality of small triangular or similar shaped projections which produce a texture similar to that of a vegetable grater, are arranged to project into the flow of a fluid medium which passes over the fin in a manner to split a part of the flow into spiralling flow patterns which curl along the surface of fin downstream of the projections and transfer heat from said surface to the fluid medium or vice versa.
